Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468222, here are decompositions:

  • 103 + 2147468119 = 2147468222
  • 409 + 2147467813 = 2147468222
  • 421 + 2147467801 = 2147468222
  • 463 + 2147467759 = 2147468222
  • 643 + 2147467579 = 2147468222
  • 751 + 2147467471 = 2147468222
  • 829 + 2147467393 = 2147468222
  • 883 + 2147467339 = 2147468222

Showing the first eight; more decompositions exist.
